HELP PEOPLE I AGAIN FORGOT EVERYTHING

Mathematics
1 answer:
Zolol [24]2 years ago
8 0

Answer:

9

Step-by-step explanation:

Create a proportion

\frac{x}{12} = \frac{63}{84}

84 divide by what gives you 12? 7

So divide 63 by 7, and you get 9.

This doesn't work with all of these problems so you can always cross multiply then divide.

12(63) = 756

84(x) = 84x

84x = 756

84x/84 = 756/84

x = 9

Hey there,

In order to solve this equation we are going to subtract 2/3 by 3/4.

To add or subtract fractions we need to make sure that they have a common denominator:

  • 2/3 and 3/4 (common denominator would be 12) so 8/12 and 9/12

Now that the denominators are the same we can subtract the two fractions:

  • 9/12 - 8/12 would equal to 1/12

That means that 1/12th of the wall still needs to be done.

Therefore 8/12 of the wall had been painted green at the end of Tuesday.

Hope I helped,

Amna
